I have heard the same and there is some discussion on medical fora, but I think the general view is that there is not good evidence of that. There are a couple of mutations of Covid around, but that has been the case for some months. The case fatality rate has dropped a bit recently, which might be because it hit the most vulnerable first, and is now working through slightly tougher patients with a lower kill rate.
Treatments are also better now. at the start it was treated like a conventional pneumonia, but now different oxygenation protocols are used and the focus on stuff like thrombotic complications is much sharper.
On the other hand, we are also learning that a lot more people have residual disease, mostly due to the inflammatory effects of the virus, including thrombosis, liver, renal and brain effects. Patients who seem to get better initially and then suddenly get worse around day 7 have usually had an inflammatory episode, with an outpouring of hormones and various natural immune cells in what is known as a cytokine storm. That might explain why BAME or people with diabetes or hypertension do worse, they have a heightened basal state of inflammation, so are part of the way down that track already.
Covid remains a nasty disease and if you get it, have a miserable week in bed then get back to normal, you have been fortunate.
The highlighted bit is certainly true, I did a bit of reading, found the case/fatality ratio had fallen from 6% on 24 June to 1.5% on 5 August, a four-fold drop in under six weeks. (Oxford university study)
Also as you say another important change is the age of new infections. At the peak of the UK's outbreak in April, 75% of people catching the virus were aged over 75, but in recent weeks the balance has shifted, with more found among working-age people. (Sky news article)
They don't get hit as badly by COVID-19, which brings the case fatality ratio down.
(Obviously if it starts getting out of control in the young it will again spread to the more vulnerable parts of the population)
As before the best places to look to see what is going to happen here are France and Spain, where cases are rising fast, but deaths and hospitalisations are still low.
Personally I feel optimistic that it is not going to go the same way as it did in March.
Still not convinced of the accuracy of the test either as both my wife and another lady on the 4 bed ward tested negative (4 times now) after a positive test. Unfortunately it has delayed her Transfer and treatment.
