Just wanted to throw this in, even though it’s not completely relevent. I am in one of R’ Scheinberg’s zatza”l yeshivos and saw him on a regular basis. Although I never saw them with my own eyes, many of my freinds have seen his techeiles tzitzis. I have a freind who was very close with R’ Scheinberg for the past year, and he told me he has seen them with his own eyes. I have multiple rabeim who married grandchildren or R’ Scheinberg and have also told me that he has at least 1 pair of techeiles tzitzis.
