I am not a fan of LeCarre or Potter, so I cannot comment on the programmes you mention.

However, I must correct you on one thing...

You write, 'Thank you Great Britain for holding up the highest standards of theatrical and film production, brave and groundbreaking, starting with Patrick MacGoohan's "The Prisoner" series in the sixties and never letting up.'

Starting with "The Prisoner" (1967)!
No! No! No! No!
Your education in British TV is sadly lacking, I fear.

It started six years earlier with the all-time classic series (161 episodes): "The Avengers" - January 1961 through to September 1969, and one of the most popular television series of all time.
Wonderful stuff. Complete and utter nonsense, but wonderful entertainment all the same.

BTW. It is not done in the UK to mention the 'B' awful recent film with whoever it was sorely miscast to play the lead roles of Steed and Mrs Peel.

Anyway, my most enduring memory of "The Prisoner" is my being in hospital and pleading with the Ward Sister to let me out of bed and into the TV room to see the first showing of the final (and truly bizarre) episode. Fortunately, the Sister took pity on me and had me wheelchaired through to the TV - and, yes, it was worth the effort
