Got no idea how you can be so sure Andy, it will be marginal. It might be fine, it might be fine some of the time, it might be blocked all the time. The only way to find out is to sit there and see with your own eyes.
Of course if that bloke standing there is 6'7" then that changes it a bit as that line would start lower down, but that's why I'm NOT saying it will definitely be blocked. We wait to see.

I've also maintained all long I don't see this as a restricted view even if the corner flag is not seen. It's a miniscule part of the pitch.
