It's not that Premiere Pro cares about image quality above all else, because it does use GPU-accelerated decoding. It's that Premiere only uses Intel's integrated GPU for decoding and not with Nvidia's or AMD's GPU decoder. Quick Sync's quality is worse than NVENC's these days so it's likely more along the lines of Intel contributed the patches than Adobe not wanting it out of purity reasons.
