Are all WOLEDs like this?

I'm testing this LG 32GX870A-B (4K 32" WOLED) and it seems to have both black crush and color banding making color gradients not appear as smooth as they should.

Elden Ring example: https://imgur.com/a/nbc3ogr — what would be a pretty smooth gradient on a different monitor is showing abrupt edges on this LG monitor.

Me slowly adjusting brightness: https://imgur.com/a/ukvfXF0 — this doesn't adjust the entire image evenly, seems to be weirdly shifting where the hard color jump is within the gradient. Also I can't completely get rid of the black crush, increasing Black Stabilizer helps a bit but it makes everything too bright. And even 100% Brightness still has black crush.

From what I'm reading this LG is using the same 3rd gen WOLED display tech as the previous 32GS95UE-B model, and ASUS models like the XG32UCWMG, XG32UCWG, and PG32UCDP. Weirdly enough I can barely seem to find anyone mentioning these issues in Amazon/Best Buy comments or even YouTube reviewers like Monitors Unboxed... so I'm wondering if I just got a defective unit or if all WOLEDs are actually like this and this is just a normal flaw people accept?

I'm trying to decide whether I should get a replacement unit, or try a different WOLED like the ASUS XG32UCWG... or switch over to QD-OLED entirely.

Appreciate any advice/suggestions, thanks

ps: I've already tried everything I could think of but nothing has worked so far: OSD settings (tried all game modes, Brightness, Gamma, Black Stabilizer). Gamma calibration in Windows 10 (Display Color Calibration). Both SDR/HDR modes. Different refresh rates: 60hz, 144hz, 240hz. Both the DisplayPort/HDMI cables that came with monitor. Display settings set to 8/10/12 bpc, and Full RGB 4:4:4 (not Limited) in AMD adrenalin settings. Installed LG Switch software but there are no firmware updates at all for this monitor. And I also tried connecting monitor to a different computer (laptop).

Finally decided to upgrade my old 27" TN 1080p panel from 2010 to this 4K 32" WOLED LG 32GX870A-B.

However I noticed black crush and gradient banding in some games/videos.

Is this issue likely to be fixable by requesting a replacement unit of the same model, or is this a firmware issue?

I've tried pretty much everything:

  • OSD settings (tried all game modes, Brightness, Gamma, Black Stabilizer): Some settings help a bit but this basically just shifts where the banding occurs, it doesn't go away completely.
  • Gamma calibration in Windows 10 (Display Color Calibration)
  • SDR/HDR
  • DisplayPort/HDMI
  • Display set to 10 bpc / Full RGB 4:4:4 in amd adrenalin settings.
  • Installed LG Switch software but there didn't seem to be any firmware updates available for this monitor.

Should I try requesting a replacement unit or any other ideas?
