The main gain from Lovelace is the die shrink from 8nm to 5nm (it's listed as TSMC 4N, but this is actually 5nm), so if you're doing the die shrink anyway, you're getting most of the benefit of Lovelace.
We know the Switch 2 has some Lovelace features because it was in the T239 leak (I forgot what it was), so they did take a few things from the Lovelace chips.
The other thing I believe Lovelace has is Frame Generation, but it's kinda pointless for Nintendo because Nvidia frame generation doesn't really run well unless you are getting 60 fps, so it's only useful for frame rates above 60, which most televisions don't support and who knows if the Switch 2 screen is even higher than 60 Hz. Ray reconstruction is still supported by Ampere chips if Nintendo ever wants to use that.
My guess is if the chip is 5nm Ampere shrink may have saved a few bucks, not go all the way with a Lovelace chip if you're not using the Frame Generation functionality anyway.
