It appears Shout factory has done an about face and has admitted the original Blu-ray release was ....er, substandard... and is using new (hopefully) true HD masters for the re-release of the collection and anyone who is getting replacement discs:
"Thank you for your recent purchase of the Bruce Lee Legacy Collection. We’re sorry to inform you that you have received a set that includes discs that do not meet our highest standards of quality assurance, and therefore we will be sending you replacement discs on or around September 16th.
The affected discs are all four Blu-rays, for which we have found improved hi-rez masters, and discs 10 and 11, which inadvertently contain content swapped from each other.
No action is required on your part. This email is simply intended to let you know about this problem and the steps we are taking to rectify it. Thanks again for your order."
Glad to see Shout owning up to the screw-up but Cliff McMillan needs to publicly apologize for either being too clueless to realize these were upscales or outright lying.
