Anyone got one and care to advise?

I have a LG model...

My new laptop has an OLED screen, and is so much better than the
previous LCD. Especially not changing with viewing angle.

Yup the big wins are massive contrast ratios, and very wide viewing
angle. Nicer to vie in low light as well, with no backlight bleed
through.

Downsides include slightly lower peak brightness[1] than some backlit
sets, a screen that can accumulate some patchy "noise" visible in dim
areas (it tends to clear itself, and the sets usually have an option to
wipe it). There is also a possibility of something akin to screen burn
on areas where a static bright graphics is held for too long - that can
reduce the output of a colour in a area)

That does worry me, as I use the set for family Zoom meetings (HDMI lead
from a PC). Leave it on tile so I can see everyone at all times. So a
fairly static pic for an hour or so.

Its not as dramatic as screen burn, and you can't for example see the
image on the unlit screen. You also generally can't see it on a normal
picture. However you might see it on a flat area of *some* colours.

For example our TV gets used for youtube, and one of the on screen
gadgets is a search button, marked with a bright yellow swatch (to
indicate press the yellow button):

Now against a normal picture, it leaves no impression:

(images just being the stock pictures it cycles through if it has
nothing better to display)

However, if I manage to stick a solid area with a high red content in
that corner:

You can see a slight darkening. With time displaying other things it
fades a bit. Running the "de-noise" will also fade it a bit.

That's quite a vivid illustration of the effect. I don't use my LG TV's
Youtube app much, but doesn't the yellow thing disappear once you start
watching a video? Does on mine.

Yup it does, although its static all the time you are on the menu
scrolling through videos etc.

Oddly the peak level red youtube logo itself seems to leave no
impression. So its colour selective as well.

The station branding logos too - they don't seem to leave an imprint. Can't
say I've noticed any problem with mine.

As I said, it quite subtle, and only shows with some colours IME (also
mine is a 2016/17 model so later ones may have tuned it out more.

On the TV (a 55" LG), stunning picture, at least compared to my other TV - a
well reviewed LCD. Seems sharper with colours more vivid, black blacks, and
all maintained across almost any viewing angle. The Atmos sound is quite
decent as these things go too.

On mine I find the most noticeable transformation is going from normal
to HDR content (HD to 4K is "better" but not massively so). The HDR
difference on the OLED is far more profound an improvement than you get
on any of our LCD/LED sets.

(HDR was improved further when I configured the source devices to
increase the peak brightness they would deliver in HDR mode - by default
they use quit conservative limits).

The only downside I can think of is the near mirror like screen reflects just
about anything. And I'd have preferred something smaller - 55" is too big for
my lounge.
Mine is reflective, although not totally flat - so there is some breakup
of reflections if you look at it obliquely.

I think I would have gone for 60 or 65, but it would fit in the
furniture I made for it, so 55 is ok. Atmos is handled by the AV amp
rather than the TV (did not seem worth spending extra on TV audio since
I was not going to use it much). (although I only have a 5.1 speaker
setup, so probably don't get the full effect from atmos)
