After reading the scans, I'd say Surfer got a power up in that he became a herald again (Or at least released his "mental blocks"😉. It's had a positive impact on his average performance, at least around the Annihilation era. Not sure why this is such a big deal though. It matters so little in the long run that it's not like his previous fights become inadmissible (Which is why I think some people are against it, harder to lowball if people say it doesn't count).
The Thanos power signature scene was clearly also another example of power. The entire context, including Surfer's struggle points to this. It in no way means Surfer is the equal of Thanos in power however. So you can breath easy insane titan. It's not what Delph is suggesting either.

Karnilla also got a powerup, problem?
Not that I know of but the scans posted contribute nothing to the discussion regarding Surfer's power up one way or another.
