You’re likely noticing several other factors. Scalded milk is much larger impact via higher temperature for far longer.

The real test is to blind taste milk immediately before and after pasteurization and I couldn’t tell the difference with High-temperature short-time which only hits 71.5C for 15 seconds.

At home you can try a blind taste test after heating to 60C for 20 minutes, but we use HTST because it’s basically undetectable. UHT has a longer shelf life, but there’s just a hint of a taste difference.
