A question for those more knowledgeable / versed in expert flyer.

Am looking at flights to BKK over the next couple of days and the following scenarios are coming up:
1. Flight is zeroed out in Y / 4 seats + multiple ‘paid’ seats showing in the seat map / EK only offering Business class to purchase on their app
2. Flight is showing Y5 E5 R5 W5M5 B5 U0 K0 Q0 L0 T0 V0 X0/ 10 seats + multiple ‘paid’ seats showing in the seat map / EK only offering Business class to purchase on their app

Is there a particular way to decipher availability vs seat map?

I know it was briefly discussed here earlier, but is the assumption that EK will op-up PAX to the extra leg-room seats rather than selling them as standard revenue seats?
