Hell yes. The signs provided are certainly not as specified in TSRGD. The LA's misguided attempt to increase visibility may well have compromised recognition.
I've thought a good deal about this. The rectangular information signs with white backgrounds look more like the sort of thing that you'd see outside a discount store advertising the latest bargains, and thus something that a car driver would quickly discount on scanning. Those signs have lots of text, which you wouldn't have time to read. Since they don't follow the TSRGD principles (which they must to be granted special authorisation) of shape, size, and colour a reasonable person with the high workload associated with city driving, could well miss the actual message.
WRT the no-entry signs themselves. They are LEDs on a black, rectangular background that has a black frame and have the shape and form of self-illuminating advertising hoardings. TSRGD provides for grey or yellow backboards, but not black - so a black rectangular sign with bright lights is very likely to be seen as advertising and discounted after the first scan.
Now for something that I suspect the authorities haven't considered: the protanopic anomalies that affect one in eight of the male population but signficantly fewer females. This is a reduction in sensitivity to red sometimes called red/green colour blindness. I'm affected and so can say with some authority that those "no entry" signs are not the correct colour - to at least one in eight men they're orange, not red. The double whammy is that monochromatic sensitivity isn't reduced, so the brighter a red light shines, the harder it is to identify that it is red. To me, those "no-entry" signs look more like advertisements for Sunshine Holidays than road signs.
There are very good reasons why all road signs should at least comply with the general principles of TSRGD - and here Manchester City Council have shown us why in spades!
Edited to add: Until I saw the original video some weeks (perhaps months) ago, I didn't know that rising bollards existed. This is a new development about which I feel confident a significant number of road users know nothing and thus would not expect. Where is the Government campaign to say that a council near you might install these things - and warn to be on the lookout. After all, there's been a lot spent recently on warning about level crossings (which are properly documented in the Highway Code and for which appropriate signs exist in TSRGD) but I've yet to see one advert on TV or in the paper to make the public aware that these abominations (that do not appear in the Highway Code or TSRGD) are in use.
