Yes:
Are you saying that it is impossible for me to provide sufficient evidence?
We would have to observe this ourselves in real time. We just simply will watch the 9:30 AM US Eastern time bar form for SPY and then re-download the historical data for that minute. We would not expect any change.

Given that other major trading platforms with consolidated feeds also have volume reliability data issues and that the out-of-trade filter you are using cuts volume counts by 30-50%, I have reasons to doubt that a new feed will simply resolve the issue.
Your doubt is incorrect. There is a world of difference between what we use now and the direct CTA and UTP feeds.
