You can just look at the Software figures since the launch of the PS4 and notice the trend, PSV might not have been successful but it sold close around 50 million software the majority of which was 3rd Party, this year the physical sales within the Famitsu Top 100 will be another sharp decline for the PS ecosystem and next year sales will decline further. Despite 2018 being the PS4 peak due to MHW it's still performed worse than 2017 which was the last year PSV got meaningful support.
- PS4/PSV/PS3 2016 - 11.932.290
- PS4/PSV/PS3 2014 - 11.199.346
- PS4/PSV/PS3 2015 - 10.382.176
- PS4/PSV 2017 - 9.462.066
- PS4/PSV 2018 - 9.228.298
- PS4 2019 - 7.181.200
Overall once it became clear that the audience of the PSV was transitioning to the Switch rather than to the PS4, it's basically ensured that a lot of 3rd Parties that were successful because they were able to have cross-platform games in the PS Ecosystem, will no longer be able to stop the decline of their franchises without prioritizing the Switch.
