Yes I'm pretty sure we've all seen this. Prior I was seeing a white box around white text on a black background and around the white 'grab' bar that appears at the bottom of most apps. Now the blooming isn't as pronounced, no longer appearing as a box but a glow, more aligned with what I see on my MBP XDR screen. I had become indifferent to iPad blooming but now I'm definitely noticing the difference and improvement.
