Amount returned per pax is £220. If i try to get pricing for specific date (23/3) one leg economy vs premium economy, not from PKX but PVG that BA is still operating and i get the following.
Economy: £290 and WTP: £634.
Shouldn't i get per passenger more than £400?
Here is the fare breakdown per person of the original ticket. GBP 3014.78 for both.

By my calculation (using the data from the "fare calculation" line) the fare for the inbound leg was approx. £269 per person (340.01 × 0.791141).
The YQ is harder to divide up accurately, since it is not split up by leg, and would vary between premium economy and business class. For a rough indication, I looked at the current YQ for LHR-PVG (since, as you say, BA no longer operates to PKX). It's £226 rtn in PE and £329 rtn in J. So you would be looking at £277.50 for an outward journey in J and return in PE - exactly the same as what you paid.
BA generally charges the same YQ for all destinations within a given country so this is not a huge surprise, and the lack of YQ increase since your booking is explained by the fact that BA has now also imposed a small amount of YR (a further carrier surcharge).
So the YQ for your inbound journey would have been approx. £113 per passenger, making for a combined fare and YQ of £382. That being the case, you would be due 75% = £286.50.
BA's reimbursement therefore isn't a million miles off the correct figure, but it looks like they have not provided much (if any) reimbursement for the YQ that you paid. It is undoubtedly part of the fare for
Mennens reimbursement purposes since it varies by class of travel.
I would get back to them and ask them to take another look at the figures. If it is more than 8 weeks since you raised the reimbursement claim then you would probably be best served by also starting a CEDR claim for the difference, since that similarly takes time to work its way through the system.
