Comment (by Balling):

 >I cannot discern IDR-frames v non-IDR-frames, and apparently neither can
 FFmpeg or FFprobe.

 You can actually, why is it so hard for you??  ffmpeg.exe -an -i
 Ticket_11080.m2ts -c copy -bsf:v trace_headers -f null -

 then you will see that

 [trace_headers @ 000001e4ae7eef40] Recovery Point


 and then

 [trace_headers @ 000001e4ae7eef40] Slice Header
 [trace_headers @ 000001e4ae7eef40] 0           forbidden_zero_bit
 0 = 0
 [trace_headers @ 000001e4ae7eef40] 1           nal_ref_idc
 10 = 2
 [trace_headers @ 000001e4ae7eef40] 3           nal_unit_type
 00001 = 1



 nal_unit_type                                           00001 = 1

 is non-IDR I frame.
