I agree the old 25's did seem narrower than most other brands 25's but the new tyres sizing seems on par with other brands, so I'm pretty sure you're not going to get the new Corsa Evo 28's in there, they are maybe only very slightly smaller than the 28's GP4000's.
And you've not even got the calipers on in that shot which may reduce that clearance further, depending on the brakes. On my Nikor I found the 28's would rub on the front Campagnolo skeleton brake, but the older pre-skeleton Campagnolo brakes gave more clearance and it was fine. But that has a Max fork with more clearance than yours. The new Evo's 28's do seem noticeably more balloony compare to the new 25's. Sorry I can't show you any photos as I'm an idiot and I left my phone in a van in Rainham yesterday. #facepalm
I've got the new ones in 25 & 28, but both I have running on new wider style rims like Pacenti Brevet. If you have the older narrower style rims the tyre may sit more like a traditional light bulb on the rim making them taller and giving you even less clearance. So I'm pretty sure the 28's are not going to fit in that fork.
The new versions definitely last longer than the old Master's too which is good, and they were delivered super fast direct from Veloflex, but that was before Brexit kicked in so assume you now have pay more for them and wait longer for them to arrive.
