Fair enough. Coatings are distinct from the panel tech underneath them. Samsung sells their own G60SD & G80SD QD-OLEDs with a matte finish:

And Asus just released their new XG32UCWMG and XG32UCWG WOLEDs (still using last gen panels w/MLA and not the newer Tandem versions unfortunately) with a pure glossy finish:

So you can currently have either panel tech with either coating (and even turn a matte OLED into a glossy one with the damp paper towel method to peel it off). The main difference is the polarizer which does do a good job of rejecting ambient light reflections inside the panel to reduce black level rise. It can't be added to QD-OLED because it is a top-emission structure and it kneecaps brightness efficiency which is already an Achilles's heel of OLED. WOLED can get away with it because it's still bottom-emission (part of why their RGB component brightness is bad) and having a dedicated White subpixel can juice the raw nits output at the cost of color volume.

Samsung does have a polarizer-based QD-OLED panel type that they exclusively use in mobile devices and moving away from it their next-gen polarizer-less version will increase their effective brightness from 3000 to over 5000 nits:
