Did 9 and 10 potential spawn rates increase?

That matters most for how you spend hunting time. A 9/9 or 10/10 rolling in the wild is no longer something you wait on forever, so going out to look for one is a real plan rather than a lottery ticket. The rise applies to both tiers, so 9-potential and 10-potential encounters are each easier to come across than they were.

Finding one is only half of it. You still have to land the catch, and a healthy creature resists. Weaken it or stun it first, because both raise the capture rate. Throwing at a full-strength high-potential spawn is the fastest way to watch the best roll you have seen all session walk off.

Where you hunt decides what shows up. Spawns follow designated habitats, current weather, and the time of day. If you want a particular Aniimo at high potential, go to its habitat and go when the conditions suit it, rather than wandering and hoping the improved rate does the work for you.

Potential you can add yourself

Wild rolls are not the only route. Acquired potential goes up in the capability awakening tab, where you spend enhancement materials on stats. A creature you already like is not stuck at the number it spawned with, and a lucky catch is a head start rather than the whole of it.

Not settled: No figure is attached to the increase, so there is no specific rate to plan a farming route around.
