Yes, it's Hedonic Quality Adjustment [1]. If you follow through the example on the link, you see the negative CPI component, even though a) you can't actually buy the old version anymore - so you can't reap the "real" price benefit and b) the subjective experience ultimately for lots of these things is the same. i.e. a mid-level TV from 40 years ago probably gave the same hedonistic pleasure as one today. Arguably the older one gave more because of less other gadgets!
