This seems to treat one white dot as a green subpixel which bleeds 25% into the diagonally 4 adjacent red/blue subpixel. I've always seen pentile subpixels represented as groups of 2 element subpixels <a href="https://geometrian.com/programming/reference/subpixelzoo/square_pentilediagonalGRGB.png" rel="nofollow">https://geometrian.com/programming/reference/subpixelzoo/squ...</a> or diamond shaped gorups of 4 subpixels, 2 of which are green <a href="https://global.samsungdisplay.com/wp-content/uploads/2021/11/Untitled-design-2021-11-19T163245.312.png" rel="nofollow">https://global.samsungdisplay.com/wp-content/uploads/2021/11...</a>. In either case, the green subpixels tend to be smaller in response to their increased prevalence.
