I'm going to assume this is for Sunday 15 December. If it is another day then the following may not make sense. Until the flight goes into FLY at T-72 BA will maintain a buffer of usually 2 or 3 rows at the top of ET and often a buffer of one row at the back of CE so that the curtain can move without disrupting too many passengers. Once you get to T-72 then Theoretical Seating kicks and another set of logic comes into play, but since you're Gold that only works to your potential advantage.

At the time you chose row 10 then the curtain would probably been between row 6 and 7, it has now moved to between 8 and 9 due to some presumably mid priced CE tickets being sold more recently. It's currently D4 and M2. I notice the earlier KM flight is nearly full and would now be more expensive than BA. So if there are any further CE sales from D, which isn't that pricey, then there is a risk the curtain will go further back still, but you are still one row away from that, they can still sell a few more CE and you would be OK. I can't see the curtain going back to row 7, though it could happen. I think it's unlikely to go to row 10, though again it could happen. Your service is already pretty full too.

There is a further complication that depending on the precise aircraft selected for the route, there are some rows at the exit where they may not be able to have a curtain, so that brings another dollop of complexity. You're currently on a G-GAT. which is preferred for the MLA route, but it could change.

In short, yes, you are at risk. No, you are not definitely going to be moved, I think probably on balance you won't be, but that's my guess and I could be wrong. If you aren't good with risk you would move, if you're ok to live a little, um, dangerously, then you'd stay put. But the big mystery to me is why you didn't select 13E and F, the exit row?
