Why does the SCART connection use capacitors in the RGB lines? (last picture)

Doesn't that block low frequency signals (e.g. an all-blue screen)?

There's still horizontal and vertical blanking intervals.

Yes, but are the RGB signals required to be zero there?

They appear to be there for high pass filtering but the 220uF value appears to be incorrect and is likely 220pF.

220uF is correct. Along with the 75Ω terminating resistor inside the TV, that forms a high-pass filter with a cutoff frequency of ~10Hz.
