Attach rate is an important metric that shows the significance of the exclusive games for someone making a buying decision on the platform. With Sony exclusives not having a large attach rate and looking at the third party sales on the platform you can come to the conclusion that people prefer to play third party games more than first party games.
Killzone sold 2.1 and Infamous 2.8, compared with the install base its less than 5% of PS4 owners that played these games, even today in their heavily discounted prices people don't choose to play them (pity because both are great games).
Because Xbox One has the same third party games also available, the differentiating factor between platforms is the power of the PS4 which makes third party games to run better on the system.
Personaly I have a PS4 mainly because I want to play the Sony exclusive games, but all the third party games that I play I buy them for my high end pc, because I find them cheaper and because I can enjoy them with better graphics/framerates/effects etc.
The same will happen with Scorpio, the differentiating factor will be the power difference and how third (and first obviously) party games will look and play.
Just no. That won't be the deciding factor and it's not the main reason why PS4 has the dominant market share.
