Earlier we (NIST) had shared the analysis for IPv4.
Listed below is the AS_SET analysis for IPv6.
Please let me know if you have any further questions.

AS_SET ANALYSIS (OREGON6 2019-10-03:00)
The Routeviews OREGON6 collector peers with (23) ASes
*********************************************************************
Summary (for IPv6)
*********************************************************************
Total # Updates : 155659
# Updates with AS_SET : 38
Percentage of routes with AS_SET : 0.024%
# Total # ASes (globally) : 18027
# ASes that create updates with AS_SET : 27
Percentage of ASes that create updates with AS_SET : 0.15%
# Routes with AS_SET (after eliminating AS path redundancy): 38
Explanation: These are routes with unique {prefix, AS_SET, 1st AS after AS_SET, AGGREGATOR} combinations.
Out of the 38 routes with AS_SETs:
*** Routes with AS_SET that seem meaningless or malformed ***
# Routes with only one AS in AS_SET : 26
# Routes with Reserved ASN in AS_SET : 0
# Routes with common AS in the AS_SEQUENCE and AS_SET : 4
# Routes with repeated ASes in the AS_SET : 0
# Routes that are /48 prefix (aggregate) announcements : 6
Total # Routes that seem meaningless or malformed : 27
Total # Routes that seem meaningful : 11
Distribution of # unique ASes in the AS_SET : 1:26,2:7,3:1,4:3,8:1
# Routes with AS_SET where AGGREGATOR does not match the right most AS in AS_SEQUENCE : 1
# Routes with unique {prefix, AS_SET, AGGREGATOR} : 38
# Routes with unique {prefix, AS_SET} : 38
*** When there is AGGREGATOR without AS_SET ***
# Unique prefixes (with or without AS_SET) : 78625
# Unique prefixes without AS_SET but with AGGREGATOR: 8651
% Unique prefixes without AS_SET but with AGGREGATOR: 11.003%
# Unique prefixes with ATOMIC_AGGREGATE: 3823
# Unique prefixes with AGGREGATOR and ATOMIC_AGGREGATE: 3650
# Unique prefixes with AGGREGATOR and without ATOMIC_AGGREGATE: 5039
# Unique prefixes with AS_SET and ATOMIC_AGGREGATE: 2
