OK, so their video, (the sole evidence BTW), shows your car turning into the restricted street. The signs passed are not shown, so you can state this in any reps, and indeed in an appeal at London Tribunals, but it is not necessarily a winning argument. This is because the civil test of evidence is "the balance of probabilities". Your car turned left into the street, so the restriction signs would not be fully visible until the turn is started. This means, in order to fulfill their duty under LATOR 2016, the council should place an advance warning sign before the turn. And indeed they have placed such a sign (GSV September 2024): -

https://www.legislation.gov.uk/uksi/1996/2489/regulation/18I have to say, (sorry to say it), but this is a prominent sign,and I would think difficult to miss when driving. Your narrative indicates a possible timing issue, (entered street 0910, restriction ended 0915, but this is not really a candidate for a de minimis appeal. I say 'appeal', because the only place where you'll get an unbiased opinion is London Tribunals; the council will always reject whatever you say, because they keep the money if you pay-up. The big hurdle with London Tribunals is that the full PCN penalty is in play there. This is why most people just fold and cough-up, most without even submitting any representations at all.
Despite the above, there may also be a 'technical' appeal argument not related to the contravention in any way. Such appeal arguments are based on council mismanagement of the enforcement process, and have won many appeals at London Tribunals. SO wait a bit to see what may be suggested, but don't miss the deadline on the PCN to pay or submit representations.
