Edit. initially ofc, but the trend is that transistor cost isnt drastically reduced anymore from die shrinks.

If you are comparing non EUV 7nm aka N7, then barely. Otherwise no. ( EUV 7nm and EUV 5nm. ) Wafer Price are on the rise and per transistor cost isn't yet. It is not hitting the same cost reduction but per transistor cost has never risen per generation during their time of introduction.

Design Cost is the main factor in cost increase, but that bare little relevance to unit cost without specific volume accounted for.

5nm and 3nm are relevant not only because of cost but Die Space and Power Usage. Where in Mobile devices you are expecting a budget of sub 100mW for Decoding. In Laptop you have the luxury of budget increase by 10x / 1W if not more on a GPU.
