I like the places you have mentioned. The comments indicate that the first steps are to use the Street View facility at Google Maps. This answer accepts that as a given and focuses on interesting alternatives involving local trade associations and civic entities...
There is a Twitter feed @RodeoDrive whose banner note reads...
The Official Twitter of Rodeo Drive in Beverly Hills✨ Representing the
retailers, hotels & landowners on the world-renowned boulevard!
The feed includes lots of photos and videos of the retailers and shop fronts. There is also a dedicated site for Rodeo Drive listing the retailers, but the Twitter feed appears to be more vibrant and dynamic.
And finally, the city of Beverly Hills has a hash tag #BHOpenLate which is dedicated to all the shops that are, well... open late.
Unsurprisingly, given the civic presence of Rodeo Drive on Twitter, there's a Twitter feed @NewburyStreet1. Their banner note reads...
Official Page of Newbury Street League Representing Boston's most
fashionable street Check in for updates on all of the latest that
Newbury Street has to offer
Their static site is at Newbury Street League and that's where you would see the population of shops (actually members of their league). But again, the Twitter feed shows which retailers are having a sale.
the Brera in Milan
This is supported by the City of Milan's feed (@ComuneMI), their banner note reads...
Informazioni, notizie e servizi da Palazzo Marino. Linea diretta nei
giorni feriali, 9.30-18.30 | The City of Milan. Monitored
9.30am-6.30pm Monday to Friday
It covers a much broader area than shopping, but they provide a phone number and appear to engage the public via Twitter DM's.
There is also a static site 'Walks of Italy' which gives a walk-through of the Brera zone.
To learn the shops on this street you would use Street View.
Gum is arguably the most elegant shopping experience on the planet so I'll add it. There appears to be no dedicated Twitter feed offered by a civic or trade association, but the query at Red Square Shopping provides photos and video walk-through's made by random tweets. There are about 100 shops in total.
There is a static site at Gum Red Square that lists all the stores by category. For Vosstaniya Square, there's a hash tag #vistaniya but obtaining a full list of merchants to be out-of-reach.
Finally, there is a dedicated Twitter feed at @bondstreetshops and their banner note reads...
Bond Street Shops, London, Jewellery, Watches, jewellers, Bond Street,
Shopping in London, London Shops.
They have a static site at Bondstreet Shops where you can get a list of their featured shops.
Of course Google Maps can be used in shopping venues almost everywhere, Canal Street, Nevsky Prospect, Regent Street, and others.
